I'd recommend a Charter Arms Pathfinder. I've had one in .22LR with a 4" barrel for about 6 months now and have had no problems. I know they also make a convertible. Mine didn't cost an arm and a leg, shoots pretty nice groups and the trigger is smoothing out after about 600 rounds through it so far. I suspect it will continue to get better over time. Still fairly heavy, but smooth. Good luck, whatever your decision!
